[vcFormat] Extra indentation occurs when passing a struct using compound literal style

Bug Summary and Steps to Reproduce

Bug Summary:
When passing parameters to a function using a composite font style, if a struct is passed, the indentation position of the first member during initialization meets expectations, but starting from the second member, its indentation unexpectedly increases by one level.

Steps to reproduce:

1. Define a multi-member struct
2. Define a function that accepts this struct
3. Call this function, passing the struct as a compound literal, and assign values to each member of the struct using multiple lines of code.
4. Call vcFormat to format

Expected behavior:
Starting from the second member, the indentation should be the same as the first member

This is my vcFormat configuration:

@fufu1437 I don't understand your screenshot, in particular the (test) -- can your provide a full code example? Also, is this with a .c or .cpp file?

Sorry, I didn't express myself clearly, which caused you trouble.

I will rephrase this bug.

Problem Description

When using compound literals, the indentation of the first member in the initializer list is inconsistent with that of subsequent members.

Reproduction Code

// Expected format
create((test) {
    .a = 1,
    .b = 12
});

// Actual formatting result
create((test) {
    .a = 1,
         .b = 12  // ← .b is indented 4 spaces more than .a
});

Specific Behavior

· Member .a is indented with 4 spaces (correct)
· Member .b is indented with 8 spaces (incorrect, one extra level of indentation compared to .a)

Expected Behavior
All members in the compound literal initializer list should maintain the same indentation level — i.e., .a and .b should be aligned in the same column.

Actual Behavior
The second and subsequent members are indented one level more than the first member, causing the member list to be - - misaligned
